Abstract

The invention relates to a fixed wing aircraft open-water-area ditching test apparatus which is composed of a front gantry bracket (1), a middle support (2), a rear gantry bracket (3), a tail adjusting device, a throwing-in support (4), a tackle track (5), a weight throwing-in device, a damping device, a small tackle (6), a model throwing-in control device and a speed test device. The fixed wing aircraft open-water-area ditching test apparatus has the advantages that experimental requirements for fixed wing aircraft ditching under a stagnant-water state and a wave state are met, different throwing-in attitude angles of the an aircraft model are achieved, experimental projects which cannot completed in a pool are solved, and the fixed wing aircraft open-water-area ditching test apparatus is clear in design principle, and has strong operability, namely, maintainability.

Description

technical field [0001] The invention relates to a ditch landing test device for a fixed-wing aircraft in an open water area. Background technique [0002] According to §25.801 ditching (c) clause in "China Civil Aviation Regulations Part 25 Airworthiness Standards for Transport Type Aircraft" (CCAR-25-R3), "must pass the model test, or be similar to a configuration whose ditching characteristics are known To check the most probable movement and state of the aircraft during ditching by comparing them with other aircraft, under the premise that there is no reference to an aircraft of similar configuration whose characteristics of ditching are known, the developed transport aircraft must pass the model ditching Test to obtain airworthiness certificate. [0003] At present, due to the late start of my country's aviation industry, the ditching test of civil fixed-wing aircraft in open waters is carried out for the first time in my country, and there is no ditching test device in...
